9 Claims. (01. 9145) This invention relates to guiding means for applying stripes and more particularly to guiding means for paint or lacquer applying instruments.

Paint and lacquer stripes were, for a long time, applied to automobile bodies, and similar objects requiring careful work, by means of a brush handled by skilled workmen. Such hand painting was found to be very expensive and not al- 10 together uniform in the quantity of paint applied or the width of the stripe, and subsequently, stripe applying instruments were devised whereby a workman of more or less unskilled ability could applying a more satisfactory stripe and at a -lower cost. Such instruments ordinarily incorporate some sort of a guide means, inthe form of a wheel or an abutment, which is arranged'to engage with a bead or a wall adjacent the line on which the stripe is to be made and such in- 20. struments have been satisfactory except in forming the junction of an angular type of stripe.

In theformation of angular stripes, considerable difliculty has been had with a guided instrument 'in making the junction so that the'same will properly meet and at the same time not project beyond the intersection. The operator must;

be very careful in moving the instrument t-o an exact position and then raising it from the work adjacent the junction of such anangular stripe whereby consuming an-undesire d amount of time in applying the paint at the juncture of the stripe.

An object of this invention is to provide a new' and novel form of guide for a paint or lacquer applying instrument in order that an {angular stripe can be made rapidly andat the same time truly. r f "I T Another object of the invention is to provide means which can bereadily applied in a window opening which; will guide a striping instrument mats-movement around an angular reveal so that the junction thereof can be quickly andaccurately applied by an, operator. 'Still another object of the invention is to provide .a guide for a:.striping instrumentwhich'is formed .with'means which will prevent-therapplicationof a stripe beyond the predetermined limit through automatically removing theidis-t 50,pensing element from the work.

Other objects of the invention will appear from the following description'taken in connection with the drawing, which forms a part of this specification, and in'which: T

I Fig. '1 is a plane'view of the guideand a striping operation.

instrument associated therewith in which two formsof corner guide means are disclosed; Fig. 2 is asectional view of the same; r Fig. 3 is a perspective view showing the ,preferredformof guide associated with the surface to be striped,

Referring-now to the drawing by the characters of reference, 10 indicates a surface to be striped by a paint or lacquer applying instrument. This instrument includes generally a handle portion 12, body portion 13 having a guide roller Marranged atone sidethereof, andan applicator nozzle 15 arranged on the same side of the body as the guide roller. The handle 12 also can serve as the paint or lacquer reservoir and within the body 13' is preferably arranged gear mechanism which is drivenby the roller shaft for moving astream of paint or lacquer through the applicator nozzle at a rate commensurate with themovement of the roller along a surface'whichwill cause a uniform paint or lacquer stripe to be deposited from the nozzle upon the surface'transversed thereby. The nozzle applicator is preferably hinged'and a spring 16 is associated therewith to normally press the outlet end into contact with the surface transversed. The nozzle illustrated forms no part of this invention and is better illustrated and described in an application Serial No. 263,995, filed March 23, 1928, by John M. *Christman.- Any form of liquid dispensing device can be employed, however, as long as it incorporates a guide "means and a fluid dispensing me'ans'.

When an angular stripe is to be applied, considerabledifficulty has heretofore been encountered whenusin'g'instrumentsof the character setf'forthdue to the fact that-the skill of the workman;=must-; be depended upon to terminate the stripes so that a finished junction' will be I formed, and itisthe purpose of this invention to providea fixture withwhich the striping instru-i ment" can be'associated which willproperly termin'ate-the stripe ends without any delay in the The fixture illustrated includes aframe 17 hav ing a pair'l of angularly disposdguideswhich arepreferably inthe form of runways,as indicated at 18." Theserunways are formed of U- shaped members which are welded or otherwise secured to the frame and are of 'a length such that the adjacent endsterminate short'of their normal junction point- These fixed runways are preferably arranged-adjacent the edge of the frame and'the applicator roller is adapted tobe rolled in the guideway so that the nozzle 'canbe 110 drawn along the surface upon which the frame rests and preferably in a parallel relation to the edge of the frame.

thereto for rotating the same upon a pintle 23 which is fixed to the frame. The guideway-21 is formed so that it can be alignedwith either of the adjacent ends of thefixed guideway upon" turning of the plate by meansof thev handle,.and thus forms a guideway extension projecting preferably beyond the fixture frame so thatthe' in-- strumen-t roller can be guided therein and the paint depcsitedby the nozzle-to the junction ofthe stripe to be formed. Astop member 35 is fixed to the outer face of the guideway '21 and has end portions projecting-beyond each end thereof. Rotation of the plate 20' will be limited by the ends of .the stop member engaging with the outer face of the adjacent fixed runways18 whereupon the guideway 21 will be in alignment with one or the other of the adjacent fixed runways 18 depending upon the direction of rotation.v It will thus be seen that the operator can quickly shift the member 20 so that an accurate angular stripe can be made. r

The preferred form of guideway extension means consists of movable extension members 24 associated one with each of the adjacent ends ofv the fixed angularly .disposed guide members. A U-shaped bracket 25 is fixed to the frame at the adjacent ends'of the fixed runways, forming. substantially a continuation thereof, and the guide extensionmembers-24 are fixed to pintles 26 which are pivotally mounted atpne end of the brackets 25. A coil spring 2?.is associated with each of the pintles and the associated bracket to frictionally retain the guide extensions in any position in which they are moved. The' guide extensions project beyond the junction of the stripe to be made and as they formacontinuation of the fixed guide members, the imple. ment is thus guided so that the nozzle will form;

an angular stripe beyond-the junctionpoint; g;

In order to prevent the nozzle'from engaging, the surface to be striped beyondthe junction point as the implement is rolled along the guideway,1I provide abutment members 28 which are. fixed to the under sideof the free ends ofsthe guide extensions by screws29 or any other suitable means. These extensions 30 project into the planeof the nozzle movement }while guided in. the extensionsand are provided with a beveled edge upon whichthe nozzle willrideandbe raised above thesurface being striped. Such abeveled edge is arranged so that the stripe made :byathe nozzle will be discontinued exactly'at' the junctionpoint; ofthe stripe made or to-be made by the nozzle when drawn .along the adjacent angu-.

larly dispo'sedguideway means These abutment members permit. the operatorto move the instrument at a uniform. speed and without any par- I 24,.extend beyond the endof the frame, it isnecese sary-that one mustbe. raised-When the other:

to 'be moved to form a continuation of its associated fixed guideway but this manipulation of the extensions requires very little time.

The frame, if desired, can be formed to fit within any depression so that a stripe can be formed a uniform width away'from the edge of the depression. As an exampleof this, theframe can be formed to fit into a window so that the instrument can be'guided around the reveal. Angular stripes can quickly and accurately be made on a plane or raised surface without any hesitancy by the operator in forming the junction of the stripe and with absolute accuracy.

Although the invention has been described in connect ion with a specific embodiment, the principles'involved are susceptible of numerous other applications which will readily occur to persons skilled-in the art; The invention is therefore to be limited only as indicated by the scope of the appended claims.
